Fourier ptychographi cmicroscopy(FPM) is a newly developed computational
imaging technique that can provide gigapixel images with both high resolution
(HR) and wide field of view (FOV). However, the positional misalignment of the
LED array induces a degradation of the reconstruction, especially in the
regions away from the optical axis. In this paper, we propose a robust and fast
method to correct the LED misalignment of FPM, termed as misalignment
correction for FPM (mcFPM). Although different regions in the FOV have
different sensitivity to the LED misalignment, the experimental results show
that mcFPM is robust to eliminate the degradation in each region. Compared with
the state-of-the-art methods, mcFPM is much faster
